Some of you guys got fairly close, but my estimate should not be more then a hundred or so off. I already own the case, I purchased it from Newegg.com but didn't have the time to build a system yet. When I saw that they used the same case in this contest, I went to jellybelly.com to purchase a bulk supply of candy corn, it was $81 for a 10 pound bag of candy corn so I just purchased 2 bags. I used the youtube video of them pouring the candy corn into the case as a reference,

but since I didn't purchase as many candy corn bags as they did to fill up the entire case, I of course had to section off the case so that I could fill each section individually, then empty that section and move on.
I should have a damn good chance of winning, especially since I submitted multiple entries + and - 25, 50, 100, 150 candy corns of my original estimate that I found out by filling the case with candy corns. When I submitted the multiple entries I made sure I used friends and familys computers so the IP address was different and used their address and information with their consent of course.
I like my odds of winning this or as least one of the runner up prizes, unless other people did the exact same thing as I did. If you want to know what I did with all the candy corn, I kept a few pounds for myself, and gave a bunch of it away to friends, family, and alot of it to trick-r-treaters that rang my door bell on Halloween.
